A kind of rotary activated tool electrode holder
Technical field
The utility model relates to a kind of rotary activated tool electrode holder, belongs to tool-electrode clamp art.
Background technology
At present, during shaping electric machining, workpiece to be machined is by location and be put on workbench with clamping element or with the gravity safety of workpiece own.Workbench often makes X, and Y moves, to adjust the relative position of workpiece to be machined and shaping jig electrode.And tool-electrode is vertically set on above workpiece to be machined by vice clamp.During as large workpiece multiple need be processed, will workbench be changed, or rotational workpieces secondary clamping, substantially increase production cost.
Utility model content
Object: in order to overcome the deficiencies in the prior art, the utility model provides a kind of rotary activated tool electrode holder.
Technical scheme: for solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of rotary activated tool electrode holder, comprise clamping part, also comprise center joint pin, arc-shaped guide rail, described center joint pin is inserted clamping part center and is connected by axis of rotation, described arc-shaped guide rail is separately positioned on clamping part both sides, and the two ends of arc-shaped guide rail are bolted on clamping part; Described center joint pin is also provided with adjusting bolt, and described adjusting bolt is all through arc-shaped guide rail.
Described clamping part is symmetrically arranged with opening groove.
Described arc-shaped guide rail is set to semi-circular structure.
Preferably, described clamping part adopts stainless steel.
Beneficial effect: a kind of rotary activated tool electrode holder that the utility model provides, by adjustment adjusting bolt, be the center of circle with rotating shaft by clamping part, arc-shaped guide rail is that track rotates, thus adjusts tool-electrode fixing on clamping part and the relative position of workpiece to be machined easily.The design's simple structure, easy to use, cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of rotary activated tool electrode holder, comprise clamping part 1, also comprise center joint pin 2, arc-shaped guide rail 3, described center joint pin 2 is inserted clamping part 1 center and is rotationally connected by rotating shaft 4, described arc-shaped guide rail 3 is separately positioned on clamping part 1 both sides, and the two ends of arc-shaped guide rail 3 are fixed on clamping part 1 by bolt 5; Described center joint pin 2 is also provided with adjusting bolt 6, and described adjusting bolt 6 is all through arc-shaped guide rail 3.
During use, two bolts 5 are each passed through symmetrically arranged opening groove 7 on clamping part 1, and are fixedly connected with tool-electrode 8.By adjustment adjusting bolt 6, allow clamping part 1 with rotating shaft 4 for the center of circle, arc-shaped guide rail 3 rotates for track, thus adjusts tool-electrode 8 fixing on clamping part 1 and the relative position of workpiece to be machined easily.
The above is only preferred embodiment of the present utility model; be noted that for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
